Answer 1

dfMerged不是函数。当您像这样创建时：

def dfMerged():
        print('This is function')

dfMerged() #Result -- this is a function

然后是一个函数。

Count = df.groupby("user_id", as_index=False).count()
Mean = df.groupby("user_id", as_index=False).mean()

dfMerged = pd.merge(df, count, how='right', on=['user_id'])
dfMerged.head(10)
